 * Returns a stable, component-unique ID.

 * If the caller passes an override, it wins. Otherwise we generate an ID once
 * for the owning component via Solid's `createUniqueId()`.
 *
 * Note: `createUniqueId()` MUST be called during component setup (not inside
 * an effect) so the generated id is tied to the component's owned scope and
 * stable for its lifetime. We only call it when there is no override — no
 * point in burning a slot when the consumer already has an ID.
